RESEARCH AND STUDY ON CONCRETE STRENGTH CORRECTION VALUE OF CFT STRUCTURE

Abstract

As the result of the research of the literatures on concrete strength correction value of CFT structure, we have found as follows,
1) The result of test calculation of strength correction value Sd shows that the appropriate value for the concrete lower than Fc60N/mm² should be 5N/mm².
2) The result of test calculation of strength correction value Sc amounts to 7 - 12N/mm² recommended by Association of New Urban Housing Technology (ANUHT). We have confirmed that the value of Sd, 1) above, is larger than the value of Dp, Diaphragm effect coefficient, proposed by ANUHT.
